描述

TypeScript Version: 3.1.0-dev.20180717

Code

const o = { a: 0, b: 1, c: 2 };

Expected behavior:

A refactor exists to convert to:

const o = {
    a: 0,
    b: 1,
    c: 2,
};

and back.

Actual behavior:

No such refactor. I have to do a lot of manual editing of whitespace.

研究方向
Investigate the TypeScript formatter source code (src/services/formatting/) to understand how refactoring actions are implemented. Look for existing similar refactors (e.g., add/remove braces) as a pattern. The issue requests a toggle between single line and multi line object literals. Implement the two refactoring actions: 'Convert object to multi line' and 'Convert object to single line'. Ensure the actions appear in the IDE and work correctly for nested objects.
